Millions of mobile phone users across the UK will be part of an 'armageddon alert' system trial in a few weeks. It will see extremely loud alarms go off on devices, accompanied by an alert message.
The alarms are designed to warn people if they are in proximity to a "danger to life nearby". Successful live tests of the service have already taken place in East Suffolk and Reading, with plans to roll it out to the rest of the UK on April 23.
